Question #
R1.1 – Site Irrigation
Question
Which type of water efficient controls are used to irrigate the site’s landscaped areas?
Applicability
Applicable to all buildings (systems or equipment in the owner or landlord’s control)
Answer
Select all that apply:
Drip or root-fed irrigation
Rain and/or soil moisture sensors
Weather-based controllers
Pressure regulated head
Smart scheduling
Stormwater capture
Landscaping does not require irrigation
None of the above
- N/A – there are no existing exterior landscaped areas
Description
Water-efficient irrigation controls reduce water consumption.
Requirements
Indicate which type of irrigation control is in place at the building and used to irrigate 80% or more of the landscape
Documentation
- Photos, specifications, excerpts from landscaping contract etc. showing example of specific strategy implemented

Other Notes
- Drip irrigation: Water lines with low flow, dripping applicators spread throughout the irrigated area to more conservatively distribute water.
- Root-fed irrigation: Applicators are below ground and close to the roots zone of plants.
- Soil moisture sensors: Moisture sensors are placed in the soil of the irrigated area and communicate with an automatic scheduling system to adjust scheduling based on the real-time moisture levels of the irrigated area.
- Rain sensors: Precipitation sensors placed in the irrigated area communicate with an automatic scheduling system to adjust scheduling based on previous rainfall on the irrigated area.
- Weather-based controllers: Can be either a Smart or Central Controller. Must be WaterSense approved
- Smart scheduling: Manual scheduling based on an interaction of factors to maximize the efficiency of water use in irrigating plants. Considers the following: timing (to reduce evapotranspiration, best at night or away from peak sun and heat loads); flow rate and distribution of irrigation system; slope; soil type and infiltration rate of area being irrigated; plant type (watering needs and root depth); seasonal changes in watering needs; and predicted and actual rainfall.
